3) Lower the hook through its space in the Middle Guide.
4) You can now release your hold on the plunger and continue the
downward movement until the hook can be dropped into the space
on the Lower Guide and the hook will rest on the Lower Slide Bar.
5) Reconnect the hook to the heddle with the small black connector
hook, taking care to avoid twisting in the Module Hook or
entanglement with adjacent hooks, heddles, or springs.
To Remove And Replace A Solenoid
The entire hook will need to be removed in order to free the plunger, hook
and spring, to provide access to the solenoid for replacement. It is
recommended that, either the Cloth Storage Apron or some large paper
(i.e., newspaper), be spread under the loom to catch any plungers (small) or
springs (very small) that may fall during this procedure.
Remove the Hook
1) Be sure the loom is turned off.
2) Unhook the small, black clip between the hook and the heddle.
3) Gently lift the hook vertically, until the bottom of the hook has
cleared both Lower and Middle Guides, but is still engaged in the
Upper Guide. Avoid entanglement with neighboring hooks or
bending by keeping the hook in vertical alignment with adjacent
hooks.
4) When the Lower Hook encounters the Upper Solenoid Bracket,
gently spread the hook by pulling the free end (with the Lower
Hook) slightly outward and continue the upward path.
5) When the hook has cleared the Middle Guide you can begin to pull
the hook down, pulling it out and toward you at a slight angle to
clear the Middle Guide.
6) When the hook is out far enough that the Upper Hook is just above
the Upper Guide, at the Upper Solenoid Bracket, locate the Solenoid
Plunger and Spring Assembly, attached to the hook. Use the thumb
and forefinger of your free hand to gently pinch the plunger, spring,
and hook. (Do not use any type of pliers or grasping tool for this, as
you may damage the plunger, spring, or hook). It may be
necessary to gently push in adjacent Plungers/Hooks to allow room
for your fingertips; this will not harm these units.
